Subject: [PATCH v2 00/15] mtd: maps: physmap cleanups
Date: Fri, 19 Oct 2018 09:48:53 +0200	[thread overview]
Message-ID: <20181019074908.13226-1-boris.brezillon@bootlin.com> (raw)

Hello,

This is an attempt at merging physmap_of.c, gpio-addr-flash.c and
physmap.c. The rational behind this decision is code sharing and
consistency with what's done in other parts of the kernel:

- physmap_of is just adding OF/DT support to the physmap logic, and we
  usually put that code in the pre-existing driver instead of creating
  a new one

- gpio-addr-flash is just an extension of the physmap logic which is
  needed when the platform does not have enough native ADDR lines
  to address the whole flash. Again, I think this core belongs in the
  physmap driver

Patches 1 to 9 are just cleanups, and are not really related to the
merging of physmap_of and gpio-addr-flash into physmap.c.

Patch 10 to 13 are doing the actual merging work, and patch 14 is
documenting the addr-gpios property that has been added to support
the gpio-addr-flash on DT platforms.

Patch 15 is a cosmetic change proposed by Ricardo.

Regards,

Boris
